Skill Level Beginner
In this lesson, we're going to create a custom stringer. It used to be that you had to add an extra, funky railing at the bottom of a railing system to simply pose as a stringer. It kind of worked but then again it kind of didn't. New to Rabbit 2013, you can add an independent stringer. The objective of this course is to create a hosted profile family for a stringer. We will then create a new support type within the model. Lastly, we'll apply it to our stairs. To get started, find the Revit model called panels and Stringers and follow along.
As you can see from this example, we have a new independent stringer with a really cool profile added to it. (audio playing) To accomplish this, we need to make a family and load it in the project, just like we've been doing all along. Go to the purple R or Program button > New > Family. Let's scroll down till we find profile hosted. This means it's going to be hosted to the staircase. If we look at the two reference planes, we look at the vertical one, this is wall face.
It's not actually a wall face, it can be any kind of face. If we look at the vertical one it center front back like we're use to. If you look at the pen you realize we can't move these graphing plans. They serve as the base point for a family. Let's create some more reference plans. On the Create tab click the Reference Plan button. On the Draw panel, click the quick lens button. Let's put an offset of 12 inches. What we're going to do is offset the horizontal line down 12 inches. The next task is to offset the vertical line in 2 inches. With the reference plains set, it's time to add our dimensions, hit escape a couple of times.
On the Modify tab click the Align Dimension button. Always start at the fixed origin reference plans. So lets start at the dimension from the left to the right and pick a point. (audio playing) And again a fixed reference plan. From the top (audio playing) to the bottom, pick a point, hit Esc a couple times. Perfect. It's time to start drawing our profile. On the Create tab, click the Line button (audio playing) and follow along. (audio playing) First thing you want to do is pick these planes.
So on the Draw panel, click the Pick Lines button. Make sure the lock button is checked on on the Options toolbar. Pick the first line, pick the second line, pick the third line and hit Esc. Let's clean these lines up. On the Modify tab, click the Trim button or type TR. (audio playing) Trim these two lines. So they're cleaned up. Hit Esc a couple times. Now, let's try the face of the profile.
On the Create tab, click the Line button and follow along. On the Draw panel, make sure the Line button is picked. It should be by default, but just make sure. Let's count this intersection and draw a line down it, 45 degrees and three quarters of an inch. (audio playing) Pick that point. Let's come down and inch and a half. (audio playing) Pick that point and at 135 degrees, draw your line back so it hits the reference plan again. Now the next thing you want to do is draw a line down 1/2 inch.
The next line is actually going to be an arc. So click on the start end radius arc button and pick a point down 3 4ths of an inch. (audio playing) And draw an arc in. Draw a line again. Let's draw one more line at a half an inch, then hit Esc. Next step is to mirror all this stuff down to here. So what I want you to do (audio playing) is pick a crossing window. That means move your cursor up to the upper left-hand point. Pick a spot, hold down your mouse, and drag it down until you see those items are selected. Once these items are selected, let go.
On the Modify tab, click the Mirror Draw Access button. Find the midpoint of the left line and pick it. Come straight over horizontally. Once you see the horizontal button show up, click that point and hit Esc. (audio playing) Let's clean this up a little bit. You can click the trim button or type tr for trim. (audio playing) Click the top line, (audio playing) click the 45 degree line. Pick the bottom line. Pick the 45 degree line.
Hit Esc a couple times. (audio playing) Last thing we're going to do is add a cool little bull nose into here. And the Create tab, (audio playing) click the line button. On the Draw panel, click the Start-End-Radius arc button. Select this endpoint. Select this endpoint and drag it out until it locks to the bull nose. Pick it. Hit Esc. Awesome. It's a pretty extreme stringer but hey, it's all practice right? (audio playing) What we're going to do now is physically save it.
So, click the purple R and go save as family. Let's save it as stringer. (audio playing) Click the options button. Make sure you're only having one back up. Click OK. Click Save. Let's click load into project. Here we are. Now it's time to add the stringer to our stairs. Go ahead and select the stairs. Click on Edit Type. What we're looking for are the supports. The red support is stringer closed.
The right support type is stringer two inch width. That's what we're going to modify. Go ahead and Click on the little Builder Button here. Material is fine, we can leave that by category. The section profile, however, we want to change that. Let's go to stringer, stringer. Let's flip the section profile. Let's duplicate this and let's call it stringer-fancy, (audio playing) because it is quite fancy. (audio playing) Click OK.
Let's click OK. Now, for the left support, string your clothes as fine. But the left support type. Let's make sure that that's stringer fancy. (audio playing) Hit OK. Hit Apply. And then hit OK. And you'll see that your string is added to your stairs. It's pretty cool. (audio playing) We can also zoom over and look what it did to the spiral stairs. If we just select this wall, it'll kind of ghost it out.
It didn't put the entire profile on there, but it still added something. It's kind of neat, right? So that's pretty complete. If you think about it, stairs are basically comprised 90% families. There's not too many items that pertain to stairs that we haven't modified in this course. Being able to create a separate profile, and dedicate it to just a support, is awesome.
